compare playback file with the recorded file

[charlamenan]

i am working with audio data ,I want to compare the recorded audio file of any audio format (.wav, .mp3 ,aac etc ) with the input file used for playback and say if both are same ,do not want byte wise comparison (bytes will not be same as a windows player is used for playback and there could be processed data )but to say recorded quality is good and has same sound (noise and glitch free) ,How do i do that ?

i could play a .wav file and record it using loopback spekaer method .
Now i have two files ,one is input file used for playback and another one is recorded music file(of the played file) ,how do i say that recorded file is noise and glitch free and sound is same as input file used for playback
